Abstract

Cette poudre à mouler, caractérisée par le fait que le rapport pondéral CaO/SiO2 s'échelonne entre 0,50 et 1,20, comprend un composé, ou plus, sélectionnés dans le groupe constitué par un oxyde, un carbonate et un fluorure d'un métal alcalin, d'un métal alcalino-terreux et d'autres métaux, et de 0,5 à 5 %, en pourcentage pondéral, de poudre de carbone. La teneur de cette poudre en LiO2 est comprise entre 1 et 7 % en pourcentage pondéral et la concentration en F est comprise entre 0,5 et 8 % en pourcentage pondéral. La température de cristallisation de cette poudre est comprise entre 1000 et 1200 DEG C, sa tension superficielle est de 250 dyn/cm ou davantage et sa viscosité eta (poise) satisfait à une formule relationnelle incluant un taux de coulée V (m/min) : 6,0 < eta V < 100,0. La structure de cette poudre à mouler est telle que la poudre servant à mouler la plaque est quasiment exempte d'enchevêtrement dans le moule et que le coulage en continu demeure stable.
